2.1 TRW, INCORPORATED DEMONSTRATION PROJECT - BETHEL, ALASKA
Energy Systems Group
One Space Park
Redondo Beach, CA 90278
The site of the TRW demonstration will be Bethel, Alaska. The energy
source to be used for the demonstration is waste heat from the power plant that
is owned and operated by the Bethel Utility Corporation. TRW will investigate
the possibility of storing this waste heat in an aquifer beneath the permafrost
at a depth of approximately 400 ft. When the hot water (less than 1000C) is
recovered from storage, it will be used for space heating of several public
buildings, including the Bethel hospital.
Bethel is in southwestern Alaska on the Kuskokwim River. It is the
regional center for trade, transportation, administration, health care, and
education. Bethel is well suited for demonstrating ATES because it is typical
of many small communities in northern areas.
Bethel, like many isolated communities in Alaska, uses diesel generators
for power. The energy from cooling water and exhaust gas is usually wasted.
This waste heat can be used as an energy source when hot water generated by
the cooling system is combined with hot water generated in heat exchangers
installed in the exhaust stacks. The injection temperature of the heated
water will be in the low temperature (about 1000C) range.
